The question is, how do the companies make up for it? One answer lies on the opposite end of the spectrum: high-end super-duper-computers often take advantage of the raw computational power of GPUs. That same processing efficiency is opening up new (final) frontiers -- Nvidia's helping a Lunar X team in their quest to go to the moon, Alice!
